Abstract
Type 304 austenitic stainless steel is used extensively in the superheater and reheater sections of boilers operated for the generation of electricity in North America. On the other hand, martensitic 12Cr-1Mo-V steels, such as DIN X20 CrMoV 12 1, are used extensively in Europe for these applications. The austenitic steel is less desirable than the ferritic from the standpoint of efficiency of heat transfer, and operating experience indicates that the welds joining austenitic and ferritic components in steam piping systems are prone to premature failure during service. While the 12Cr-1Mo-V steels avoid these problems, they are much more difficult to weld than Type 304 stainless steel.
